Remove trivial cases of unused variables (3)

2013-06-27T17:34:17+00:00

Kill some of the variables marked as unused by flakes8. This should
allow to enable F841 check in the future.
Only trivial cases with no function calls and obviously pure functions
(like datetime.now(), or len()) are cleaned up here.

Part 3, split to reduce conflicts.

Fix zookeeper import and tests

2013-05-08T14:22:59+00:00

Import zookeeper.membership rather than zookeeper.membersip.
Also fixed some issues with setting up the tests for the zookeeper
servicegroup driver.  Config options were not being set before
initializing the driver leading to failures.

There is no added test for this because the bug is indistinguishable
from not having the zookeeper python modules installed, which leads to
skipping these servicegroup tests.

Allow zk driver be imported without zookeeper

2013-02-26T07:36:05+00:00

The zookeeper python module isn't widely available (e.g. not available
on Fedora), so allow the zk servicegroup driver be imported even if the
module isn't found.

This helps allow the generate_sample.sh script generate a sample config
file even without zookeeper installed.

Merge "Added a service heartbeat driver using Memcached."

2013-02-20T02:56:56+00:00

Do not use abbreviated config group names (zookeeper)

2013-02-18T22:23:04+00:00

Using abbreviated config group names just makes the config file harder
to understand, so just use full name.

Added a service heartbeat driver using Memcached.

2013-02-13T14:31:12+00:00

Today the heartbeat information of Nova services/nodes
is maintained in the DB, while each service updates the
corresponding record in the Service table periodically
(by default -- every 10 seconds), specifying the timestamp
of the last update. This mechanism is highly inefficient
and does not scale. E.g., maintaining the heartbeat
information for 1,000 nodes/services would require 100 DB
updates per second (just for the heartbeat).

This patch adds nova.servicegroup.drivers.memcached, a
service heartbeat driver using Memcached. You can reduce
DB updates with it.

Implement ZooKeeper driver for ServiceGroup API.

2013-02-07T21:46:52+00:00

The ZooKeeper driver uses ephemeral nodes in ZooKeeper to keep
track of node liveness in a service group. The Implementation is
based on the evzookeeper library to combine zookeeper
and eventlet.
